自定义分页存储过程及VB.NET 调用

ALTER PROCEDURE [dbo].[GetRecordFromPage]

@PageIndex int = 1,-- 页码

@IsCount int = 0,-- 返回记录总数,非0 值则返回
@PageCount int output,--总页数，作为返回值
@strWhere nvarchar(255) = '' -- 查询条件(注意: 不要加where)

VB调用的过程，和使用
Private Sub PageSelect(ByVal tblName As String,ByVal fldName As String,ByVal PageSize As Integer,
ByVal PageIndex As Integer,ByVal OrderType As Integer,ByVal IsCount As Integer,
ByVal strWhere As String)
Try
Dim conn As New sqlConnection
conn.ConnectionString = ConfigurationManager.ConnectionStrings("wingsbook").ToString()
Dim myCommand As New sqlDataAdapter
Dim ds As DataSet
myCommand = New sqlDataAdapter("GetRecordFromPage",conn)
myCommand.SelectCommand.CommandType = CommandType.StoredProcedure
myCommand.SelectCommand.Parameters.Clear()
myCommand.SelectCommand.Parameters.Add("@tblName",sqlDbType.NVarChar,255).Value = tblName
myCommand.SelectCommand.Parameters.Add("@fldName",255).Value = fldName
myCommand.SelectCommand.Parameters.Add("@PageSize",sqlDbType.Int).Value = PageSize
myCommand.SelectCommand.Parameters.Add("@PageIndex",sqlDbType.Int).Value = PageIndex
myCommand.SelectCommand.Parameters.Add("@OrderType",sqlDbType.Int).Value = OrderType
myCommand.SelectCommand.Parameters.Add("@IsCount",sqlDbType.Int).Value = IsCount
Dim PageCount As sqlParameter = myCommand.SelectCommand.Parameters.Add("@PageCount",sqlDbType.Int)
PageCount.Direction = ParameterDirection.Output
Dim CountS As sqlParameter = myCommand.SelectCommand.Parameters.Add("@CountS",sqlDbType.Int)
CountS.Direction = ParameterDirection.ReturnValue
myCommand.SelectCommand.Parameters.Add("@strWhere",255).Value = strWhere
ds = New DataSet()
myCommand.Fill(ds,"tableset")
Me.DataGridView1.DataSource = ds.Tables(0)
keepnum = PageCount.Value
keepcount = CountS.Value
countsum.Text = CountS.Value & " (总页数：" & PageCount.Value & ")"
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
End Sub

调用：

PageSelect("Com_Customer","id",100,1,"1=1")

使用

declare @i int , @PageCount int

exec @i = GetRecordFromPage 'Customer_info' , 'id' , 1000 , 2 , 1 , 1 , @PageCount output , 'id>14000'

select @PageCount as [out]

print @i
